Abstract
The present paper is concerned with the proposal of a seismic performance evaluation method for steel bridges with H-section members. A shell-element numerical model that can account for buckling behavior is first created to clarify the collapse mechanisms of the members subjected to monotonic and cyclic loading. Pushover analysis employing a beam-element numerical model is then implemented to examine the ultimate strain equations, which are necessary components of the failure criterion for strain-based evaluation method. Finally, based on the findings in the analysis, a seismic performance evaluation method for H-section steel members is proposed.
